I want to turn publicly available well information into a genuinely original petroleum-engineering or geology study. Your task starts with a focused literature review that pinpoints a clear gap in current knowledge, then uses real data from existing wells to fill that gap.
What matters most to me is ending up with a complete study plan that already contains the data, the analysis, and thorough documentation. I am flexible about the discipline focus—reservoir behaviour, log interpretation, drilling performance, or any other angle—provided the idea is fresh, technically sound, and demonstrably feasible. Here is the flow I expect: • Locate and reference suitable open-source well datasets. • Formulate specific, testable research objectives tied to the identified gap. • Lay out a practical methodology, noting any models, coding languages, or software you choose. • Carry out enough analysis to show the approach works, interpret the results, and explain the limitations. • Package everything—datasets (or download links), cleaned data files, calculation sheets or scripts, result visuals, and a narrative report—so another researcher can replicate the work without guesswork. Keep the writing concise, cite sources accurately, and make the analytical steps transparent. I will be available for quick feedback as the project moves from idea selection to final documentation. Skills: Research, Geology, Petroleum Engineering, Statistical Analysis, SPSS Statistics, Data Science, Data Analysis, Data Management

AI Data Automation Engineer: Source, Build, QA and Ship Data Products End to End

We are a B2B data intelligence platform. We sell signals to commercial teams: which companies are hiring, spending, moving people and warming up as buyers. Customers include large media and agency groups. They come to us for one thing: fresh data they can export.
Every dataset in the app is judged on three numbers: coverage, accuracy and recency. This role exists to push all three up, one dataset at a time. You will run whole epics on your own. That means working out what customers need, finding where the data lives, building or buying the pipeline, landing it in BigQuery, building models on top of it, checking it with LLMs and shipping it to production down to the column and cell. Then you keep it fresh. You will not be handed a spec. You will write it. We are AI-native. Claude Code, connected to our warehouse over MCP, is how we explore data, write dbt models and pipelines, and QA output. We run our own MCP servers. If you still do by hand what an agent could do, this isn't the role for you. THE LOOP YOU ARE BUILDING A customer asks for something we don't have, or have only thinly. You size the demand and decide whether it's worth building. You find the precursor data, whether that's public sources, vendors, APIs or our own engines. You scrape it or license it and land it in BigQuery. You transform it in dbt and build data science models on top of it, such as entity matching, classification and enrichment, to a very high accuracy bar. You QA every model with LLM checks against ground truth. You deploy the columns and cells that pass, through ClickHouse and Elasticsearch, into the app. You set a refresh schedule that costs as little as possible for the freshness the customer needs. Coverage, accuracy and recency go up, and you report all three. That loop is the job. A dataset that's 90% accurate but six months stale is worth less than one that's 85% accurate and refreshed weekly. You will be the one deciding where that trade-off sits. WHAT YOU BUILD: FOUR LAYERS 1. Demand → dataset. Turn customer requests, support tickets, product usage in PostHog and sales calls into a ranked backlog of data models to build. You write the case for each one: who wants it, what it unlocks and what it costs to keep fresh. 2. Sourcing: build or buy. Custom scrapers for public sources, written within each site's terms and with privacy in mind. They're built with Playwright, Apify or Bright Data and run on GCP. Vendor evaluation where buying beats building: sample pulls, match rates against our entity base, cost per useful row and refresh SLAs. You bring us a recommendation with numbers, not a list of vendors. 3. Modelling and LLM-driven QA. dbt models on BigQuery, from raw data through staging to the marts the app reads. You build the data science models on top: matching, deduplication, classification and enrichment. Automated QA uses LLMs to check, reconcile and score records before they reach a customer. You prototype in Claude Code against the warehouse and prove the model there. Only then does it go to production. 4. Storage, refresh and deployment. You decide where each dataset lives and how it reaches the app: BigQuery, ClickHouse, Elasticsearch, Postgres and Redis. You also decide what to fetch at request time and how often to re-pull, through dbt Cloud jobs, Dagster, Pub/Sub and Cloud Run. Deployment happens at column and cell level, so a weak field never drags a strong dataset down with it. Lightweight endpoints and internal tools ship on Vercel, and failures alert through Sentry and Datadog. WHAT YOU OWN END TO END - The data backlog, ranked by customer demand and cost to serve - Scrapers, vendor integrations and the pipelines that join them - dbt models and the data science models built on top of them - Vendor evaluations and build-vs-buy recommendations - LLM QA processes and the accuracy benchmarks behind them, running continuously rather than once - Storage and refresh architecture, with GCP cost per dataset - The weekly coverage, accuracy and recency report, by dataset and by field 30 / 60 / 90 - Day 30: Current datasets audited for coverage, accuracy and recency. First epic picked and scoped. LLM QA running on a schedule against at least one existing dataset. - Day 60: First new dataset sourced, modelled in dbt, QA'd and deployed to the app at column level. First vendor evaluation delivered with a recommendation. Refresh and storage cost per dataset measured. - Day 90: Two epics shipped end to end, each on a refresh schedule with ongoing QA. Measurable gains in coverage, accuracy or recency on the datasets you touched. A demand-ranked backlog for the next quarter. SUCCESS METRICS - Coverage, accuracy and recency, by dataset. This is the north star. Every other metric feeds it. - Model accuracy against ground truth. It stays high after launch, not just on launch day. - Cost per fresh record. It goes down as you optimise storage and refresh across GCP. - QA pass rate before production. Nothing ships to a customer without passing. - Epics shipped end to end. Shipped means live in the app, not stuck in a notebook. COMPENSATION Full time, 40 hours a week, $24–42/hr depending on experience. Tooling, vendor sample and compute costs are paid separately from your fee. REQUIREMENTS - You have done the full loop yourself, more than once. You sourced raw data, pulled it into a database, built data science models on it to a very high accuracy, deployed those models into a production app, then maintained and refreshed them with ongoing QA. This is the most important requirement. Your GitHub or Loom should show it. - AI-native. You use Claude Code every day, including with MCP connected to a data warehouse, to write code, build pipelines and QA data. - dbt on BigQuery in production. You have worked with incremental models, tests, sources and the cost of a careless full refresh. - ClickHouse. You know when to serve from ClickHouse rather than query BigQuery, and the cost and latency trade-offs between them. - Orchestration. You have used dbt Cloud plus Dagster or a similar orchestrator, and you think in assets, schedules, sensors and freshness. - GCP. You are comfortable with Cloud Run, Pub/Sub, Cloud Storage, IAM and keeping a GCP bill under control. - Production scrapers you built yourself with Playwright, Apify, Bright Data or similar, including rate limiting, anti-bot handling, monitoring and fixes when they break. - Strong Python and SQL. You are at home with entity matching, deduplication and schema design. - LLMs for real data work through the Anthropic or OpenAI APIs, such as extraction, classification and validation, and you can show how you measured accuracy. - Vendor evaluation. You have evaluated or integrated third-party data vendors and can explain match rate, fill rate and freshness without looking them up. - Autonomy. You can take a vague goal, turn it into a plan and ship it without daily check-ins. - GDPR awareness. You work with UK and EU data, and scraping and personal data both sit inside privacy review. - Clear written English. You will write the specs, vendor memos and weekly reports. Nice to have: Elasticsearch. Postgres and Redis. Building MCP servers in Python. TypeScript, GraphQL (Apollo Federation) or Next.js, so you can follow your data into the app. Vercel and Supabase. Terraform, GKE and Cloud Build. Clay and Make. Product management experience with data products. Our stack: Claude Code + MCP, Anthropic and OpenAI APIs, Python, SQL, dbt (dbt Cloud), BigQuery, ClickHouse, Elasticsearch, Postgres, Redis, Dagster, GCP (Cloud Run, Pub/Sub, GKE, Cloud Build), Terraform, Playwright, Apify, Bright Data, GraphQL, Vercel, Supabase, PostHog, Sentry, Datadog, Make, Clay, Linear and Slack. How we work: Async-first, any timezone. You need to be reachable on Slack and you need to ship. Hacky and shipped over polished and planned. If the first version of a new dataset is a scraper, a Claude QA prompt and one table of cells that passed, that is correct. Make it work, show us the numbers, then automate it. HOW TO APPLY: READ THIS CAREFULLY Proposals without one of these will not be read: - A GitHub link to a scraper, pipeline or data model you built yourself, or - A Loom of 5 minutes or less walking through one dataset you took through the full loop: where you sourced it, how you stored it, the model you built on it and its accuracy, how it got into production and how you kept it fresh and QA'd. Start your proposal with the word "Recency" so we know you read this far. Proposals that look like templates or are written entirely by AI will be rejected. Client's questions:

***What We're Looking For***
An experienced data architect, principal analytics engineer, or former Head of Data who combines deep technical expertise with strong strategic judgment, experience leveraging AI, and an interest in coaching others. Key capabilities include: · Data architecture and engineering, particularly Google Cloud, BigQuery, SQL, and Power BI. · Data pipelines, transformation frameworks, semantic modeling, testing, and automation. · Scalable architecture, data governance, version control, and development standards. · AI-assisted programming and analytics, including Claude Code or similar tools, with particular emphasis on secure implementation. · Natural-language querying, AI-enabled reporting, and self-service analytics. · Technology stack evaluation, technical roadmapping, and prioritization. · Technical mentorship, team development, and leadership assessment. Healthcare experience and familiarity with financial and operational analytics are beneficial but not required. ***About Us*** Armina Health is a multi-entity healthcare organization operating across multiple specialties and states. Our internal data and analytics platform integrates data from multiple EMR and operational systems. Platform: Google Cloud, BigQuery, SQL, and Power BI Where we are: We’ve made considerable progress building automated financial and operational reporting. What we need: An experienced technical leader to evaluate our existing architecture, guide our long-term technology and AI strategy, and accelerate the development of our internal analytics team. What we’re not after: Someone to take over development indefinitely. Our goal is a more reliable, scalable infrastructure and a technically capable, independent team that can increasingly operate without outside support. ***Objectives*** 1. Evaluate Our Architecture and Technical Direction Assess our existing data infrastructure, reliability, scalability, documentation, and development practices. Identify material risks, opportunities for improvement, and recommended changes to our technology stack. Help establish a practical, prioritized technical roadmap that supports our future growth without introducing unnecessary cost or complexity. We want someone who can challenge our assumptions and help us understand what we may be overlooking, rather than simply improving the tools we're already using. 2. Develop Our AI Strategy and Self-Service Analytics Capabilities We have a fairly traditional, structured analytics environment today. Data is consolidated and transformed in Google BigQuery, and recurring reports and dashboards are automated through Power BI. We want to understand what more is possible. In particular: · How can we leverage AI to make reporting and analysis substantially faster, easier, and more accessible? · Can we enable executives to ask questions of our data in natural language and generate their own initial analyses, reports, or visualizations? · Can we create a workflow where executives perform preliminary analysis independently, then engage our analysts to validate findings, investigate further, or develop more sophisticated reporting? · How should our data architecture, semantic models, documentation, and governance evolve to support reliable AI-generated analysis? · How can Claude Code, smaller specialized models, or other AI tools accelerate programming, data engineering, reporting, and automation? · What infrastructure, security controls, model architecture, and data-access restrictions are necessary to implement these capabilities safely, particularly with sensitive healthcare information? We're interested in practical solutions that build on our existing investments, not necessarily replacing our current platform. Our desired outcome is to move beyond a model where executives request reports and wait for analysts to produce them, toward one where leaders can explore trusted data independently, with analysts increasingly focused on validation, deeper analysis, and higher-value work. 3. Develop a More Capable and Independent Team Provide technical coaching, architectural guidance, and development support to our existing analytics team. Initially, we envision participation in our weekly coordination meetings, review of current technical challenges, guidance on development approaches, and direct coaching as needed. We want to improve the team's technical judgment, programming capabilities, engineering practices, and ability to evaluate new technologies. The objective is greater independence, better decision-making, and less reliance on any single technical resource or executive oversight. 4. Evaluate Our Future Leadership and Organizational Needs Assess the capabilities, strengths, and development opportunities of our existing analytics team. Help us determine: · What technical, strategic, and managerial capabilities our future Director of Data & Analytics should possess. · Whether someone on our current team has the potential to grow into that position. · What development or recruiting would be needed to close existing gaps. · Whether a full-time director is necessary or whether a stronger internal team supported by fractional technical leadership could be a better structure. We want to define the right leadership solution based on the actual needs of the organization. ***Engagement Structure*** We envision a longer-term relationship with a decreasing level of involvement as our team and infrastructure mature. Phase 1 — Initial Assessment & Technical Integration (Approximately 4–8 Weeks) Estimated commitment: 10–20 hours per week · Evaluate the existing architecture, technology stack, AI readiness, and team capabilities. · Begin attending weekly team coordination meetings and providing technical guidance immediately. · Identify risks, capability gaps, and opportunities for improvement. · Recommend an initial AI and self-service analytics strategy. · Develop a prioritized technical roadmap. · Recommend future team structure and leadership requirements. We invite candidates to propose an appropriate assessment scope, timeline, specific deliverables, and fixed fee. The assessment should be practical and proportionate to our environment rather than an unnecessarily extensive consulting engagement. Phase 2 — Roadmap Execution & Team Development (Approximately Months 3–6) Estimated commitment: 8–15 hours per week · Help the team execute the highest-priority roadmap initiatives. · Provide technical coaching, architecture review, and ongoing guidance. · Support pilot implementation of AI-assisted development and self-service analytics. · Establish and reinforce development standards, documentation, testing, and governance. · Continue developing internal capabilities and potential future technical leadership. · Reassess priorities and technical needs as we make progress. Our internal team will remain responsible for implementation. The advisor will provide technical direction, coaching, and review, with occasional hands-on contributions by mutual agreement. Phase 3 — Ongoing Fractional Advisory (After Approximately Six Months) Estimated commitment: 3-6 hours weekly · Provide continued architectural oversight and technical guidance. · Participate in periodic team coordination and strategic planning. · Advise on major technical decisions, new technologies, and AI opportunities. · Coach team members as needed. · Help ensure our architecture and capabilities continue to evolve with the business. Occasional project work may be available and would be scoped separately. ***Division of Responsibilities*** · Advisor: Technical strategy, architecture evaluation, coaching, quality review, and recommendations. · Internal Team: Development, implementation, maintenance, and documentation. · Executive Leadership: Business priorities, resource allocation, and investment decisions. We want someone who can help us build the function, not become indispensable to its daily operations. ***Ideal Candidate*** We're particularly interested in someone who has built or led a data and analytics function, has practical experience incorporating AI into modern data environments, and enjoys developing technical teams. We value independent judgment, clear communication, curiosity, and an ability to balance sophisticated technical thinking with practical, cost-conscious solutions. ***How to Apply*** Please fill out the following form: https://forms.gle/oZ3hDHGSTaesWAq29

About Akerio
Akerio is a UK-based applied AI company. We build platforms that turn messy enterprise data into scored, auditable recommendations: the next diesel price for one of Europe's largest independent fuel distributors, a risk flag on a tenant across 41 shopping centres, a credit score a bank's committee can trace back to the source record. Our models are built by a PhD team from Stanford and the University of Chicago, every output shows what drove it and how confident it is, and the platform runs on-premise or in the cloud. We are live in production across energy, commercial real estate and financial services, with 18 AI modules running in one deployment alone. We are a small team shipping to demanding enterprise clients, so the work you do reaches production and gets used. • Job: Full time • Job type: Remote The role Our retail property analytics platform, live across 41 shopping centres, finished its first delivery phase and is moving into the next: new forecasting and cash models, a retail tenant version, and a product other mall operators can buy as a subscription. Every week, client feedback, AI assistant ratings and engineering findings land in the same Jira backlog. Someone has to decide what matters, write it so an engineer can build it without guessing, and prove to the client that it was delivered. That is you. You report to our CPO and work daily with engineering, data science, design and the client's asset, leasing and finance teams. What you will work on • Backlog ownership: turn client feedback, usage data and AI conversation reviews into prioritised Jira stories with clear acceptance criteria. • Discovery with users: sit with leasing, finance and operations teams, map how they make a decision today, and find where a widget, forecast or AI answer would change it. • Specs: short written specs for each feature: the problem, the user, the data it needs, edge cases, and what done looks like. Engineers use them with AI coding tools, so precision matters. • Delivery tracking: plan sprints, track phase milestones, and prepare the input for monthly steering committee decks: what moved, what is at risk, what decision is needed. • Acceptance: run user acceptance with the client, map deliverables to agreed scope, and close findings. • AI product quality: review assistant conversations and ratings, group them into needs, and turn them into fixes to prompts, tools or widgets. • Productisation: help shape the version of the platform that a second and third mall operator can adopt without custom work: onboarding, configuration and pricing tiers. Tools you will use Area Tools Delivery Jira, Confluence, Figma Product insight Langfuse (AI conversation and quality analytics), product usage data, SQL for your own questions Communication Microsoft 365, Teams, PowerPoint for steering decks Working with engineering Written specs, Bitbucket pull request reviews for acceptance, AI tools (Claude) for drafting and analysis You do not write production code, but you should be able to read an API response, run a SQL query, and follow a technical discussion about NestJS services or an Airflow forecast run. Your first six months • First month: you know the platform module by module, have met the key client users, and own the backlog for one module. • Month three: you own the full backlog and sprint planning, and the steering committee input comes from you. • Month six: you lead discovery and scope for a new module or a new client rollout, from first workshop to signed-off acceptance. What you bring • 3 to 5 years as a product owner, product manager or business analyst on a B2B software product, ideally data or analytics heavy. • You have written user stories and acceptance criteria that engineers built from without coming back to ask what you meant. • Comfort with numbers: you can read a P&L line, question a forecast, and spot a wrong total on a dashboard. • You have run sessions with client stakeholders, including senior ones, and managed scope when they asked for more. • Basic SQL and comfort with Excel at a serious level. • Fluent English and Turkish: current client teams work in Turkish, documentation and the wider company in English. Nice to have • Domain knowledge in commercial real estate, shopping centres, retail or finance. • Experience with AI or LLM products: prompt design, evaluation, reading conversation logs. • Agile certification (CSPO, PSPO) or a background in consulting or delivery management. • Experience turning a custom client project into a repeatable SaaS product. How we work Small team, direct access to clients, and decisions in writing. We review the backlog every week, show progress to the client every month, and expect product people to argue for the user with evidence. Hiring process 16. 30-minute intro call. 17. 30-minute session: present your case to the CPO and an engineer. 18. 15-minute call with a founder. What we offer • Fully remote, with overlap on UK and Türkiye working hours. • Ownership of a live AI product with real users and a clear path to more client

About Akerio. Akerio is a UK-based applied AI company. We build platforms that turn messy enterprise data into scored, auditable recommendations: the next diesel price for one of Europe's largest independent fuel distributors, a risk flag on a tenant across 41 shopping centres, a credit score a bank's committee can trace back to the source record. Our models are built by a PhD team from Stanford and the University of Chicago, every output shows what drove it and how confident it is, and the platform runs on-premise or in the cloud. We are live in production across energy, commercial real estate and financial services, with 18 AI modules running in one deployment alone. We are a small team shipping to demanding enterprise clients, so the work you do reaches production and gets used.
• Job: Full time • Job type: Remote The role Our clients do not buy a model. They buy a better decision: which lease to renegotiate this quarter, which tenant is about to pay late, how much footfall a mall will see next month. On our retail property platform, revenue, footfall, tenant risk and mall performance models already run every month through Airflow across 41 shopping centres. The next phase adds collections and cash projections, campaign ROI, and models trained per client. You own that model portfolio: accuracy, explainability, retraining, and the step from "runs on one client's data" to "runs for every client". You work with our Chief AI Engineer and directly with the client's asset, leasing and finance teams. What you will work on • Forecasting: tenant turnover, hourly footfall per location over a 12-month horizon, energy use, collections and cash flow. • Risk scoring: tenant payment-delay risk, brand risk scores, early warnings on underperforming units. • Lease analytics: estimated rental value (ERV) and which contracts sit below market. • Explainability: every output ships with drivers (SHAP) and a confidence range a leasing manager can understand. • MLOps: moving from scheduled scripts to proper experiment tracking, a model registry and per-client training, with clear accuracy reporting back to the product. • LLM quality: the AI assistant answers questions over these numbers with 53 tools. You help design its evaluation: test sets, terminology rules, and the Langfuse feedback loop. Beyond real estate, the same skills apply to our energy pricing and banking risk work, so you will see more than one industry. Our stack Area What we use Modelling Python, pandas, scikit-learn, XGBoost, Prophet and other time-series methods Explainability SHAP Orchestration and serving Apache Airflow for monthly training and scoring runs, FastAPI compute service, MLflow being introduced Data PostgreSQL and PostGIS, Excel and ERP exports from client systems LLM Anthropic Claude via API, RAG over client data, tool calling and MCP, Langfuse for conversation and quality monitoring Infra Azure, Docker, Jenkins, Bitbucket How we build Jira, spec-first work with AI coding tools (Claude Code), code review on every PR Your first six months • First month: you know one live model inside out (data, features, metrics, failure modes) and ship one measurable improvement to it. • Month three: you own a model family (for example tenant risk) including retraining, monitoring and the accuracy numbers clients see. • Month six: you lead the modelling side of a new client rollout or new module, from use-case scoping to an advisory-mode pilot, and mentor a junior. What you bring • 5+ years building ML models that ran in production and changed real decisions, not only research or dashboards. • An MSc or PhD in a quantitative field (statistics, computer science, economics, operations research), or equivalent depth. • Strong time-series forecasting, plus at least one of: risk or default scoring, demand forecasting, pricing. • Sound statistics: you know when a backtest lies, how to handle sparse or messy client data, and how to explain uncertainty to a CFO. • Production Python: clean, tested, reviewable code an engineer can deploy without rewriting it. • Experience putting models on a schedule (Airflow or similar) and tracking them (MLflow or similar). • Fluent written and spoken English. Nice to have • Retail, shopping centre, real estate or energy data. • LLM evaluation in production: test sets, LLM-as-judge, failure analysis from real user sessions. • Geospatial data or footfall and sensor data. • Multi-tenant model training: one pipeline, many clients, different data quality. • Turkish, helpful for working with current client teams. How we work Every model starts in advisory mode next to the client's current process and earns trust by beating it on agreed metrics. You present results to client teams yourself, so you hear quickly whether a model helps. Hiring process 10. 30-minute intro call. 11. 30-minute session: present your case to the CPO and an engineer. 12. 15-minute call with a founder. What we offer • Fully remote, with overlap on UK and Türkiye working hours. • Models in production with real outcome data coming back every month. • A PhD-heavy AI team to think with.

Advisory - One call - Hackaton long short, beta neutral

We’re Sharpe Minds, a McGill team in the FIAM final challenge. We run a daily-decision, US$1bn long/short equity book on a monthly XGBoost cross-sectional return model. The model is trained on 147 firm characteristics with expanding-window validation, and the portfolio is beta-neutral and sector-ranked. Our development work shows that the phase-1 edge largely disappears under the new rules. The short-leg profits came from names below $500m, which are now unshortable. Net alpha is roughly zero on the 2021–26 development window, and costs run about 3% a year. We are hiring a quant on a short contract, ahead of the event, to: (1) rebuild the signal for the new tradable universe (≥$500m, 15% of ADV capacity limits, 15 bp half-spread, next-day execution), so the decile spread holds up in 2024–26; (2) fix the portfolio construction and turnover logic (hysteresis, multi-day execution, beta and sector neutrality) so the book is at least gross-positive against T-bill + 4%; and (3) independently audit our walk-forward protocol, including test-period tuning, look-ahead and survivorship (the 8-K corpus omits delisted firms), because the brief disqualifies undisclosed leakage. You’ll need strong cross-sectional equity factor and ML experience (Python, pandas, XGBoost), a rigorous approach to backtesting and transaction-cost modelling, and the ability to deliver tested, documented code and a short methodology memo within days. A clean, reproducible pipeline matters more to us than a high backtest number.

PokerDen is hiring a data engineer to build the game's data foundation: recording every hand, tracking how players use the game, and supplying clean data to our AI work.
PokerDen is a social Texas Hold'em game: players create an account, take a seat and play with friends in real time. It uses play chips only, with no real-money betting. The working MVP has a full Hold'em engine, real-time tables over Socket.io, and player accounts with chip balances saved in MongoDB. Hands are played out on the server, but their history is not saved yet, and there is no analytics or data pipeline. You'll build that from the start. What you’ll do You'll own PokerDen's data from the moment it is created to the moment someone uses it. In your first months, that means: 1. Record every hand. Design and build hand history storage: every deal, action, pot and result, linked to the players and table, in a format that is easy to query and replay. 2. Track how the game is used. Set up event tracking for sign-ups, sessions, table joins, chip top-ups and churn, and build the dashboards the team uses to decide what to build next. 3. Watch the chip economy. Report how chips enter and leave the game, and alert the team when balances move in ways that suggest a bug or cheating. 4. Feed the AI work. Give the AI engineer reliable, well-documented datasets for training poker bots, detecting unfair play and evaluating models. 5. Make it production-ready. Pipelines ship with tests, data quality checks, monitoring, backups and clear ownership, and they don't slow down live games. 6. Protect player data. Keep personal information separate and access-controlled, set retention rules, and support data export and deletion requests. You'll work with the full-stack engineer, who owns the game server, the AI engineer, who uses the data, and directly with the project owner on priorities.

PokerDen is hiring an AI engineer to design, build and ship the game's first AI features, and to run them reliably in production.
PokerDen is a social Texas Hold'em game: players create an account, take a seat and play with friends in real time. It uses play chips only, with no real-money betting. The working MVP has a full Hold'em engine, real-time tables over Socket.io, and player accounts with chip balances saved in MongoDB. It has no AI features yet. You'll be the person who decides how AI fits into the game and gets it into players' hands - What you’ll do You'll own PokerDen's AI work from prototype to production. In your first months, that means: 1. Build AI opponents. Create poker bots at several skill levels so players always find a game, even at quiet tables. Bots are always clearly labelled as bots, and they see only what a human player in their seat would see. 2. Protect fair play. Detect collusion, chip dumping, multi-accounting and players using bots or outside help, using game history and behaviour signals. Flag cases for review instead of banning automatically. 3. Moderate chat. Filter abuse, spam and personal information in lobby and table chat, with low enough delay that conversation still feels live. 4. Add a hand review assistant. After a hand ends, players can ask an LLM to explain what happened and what they might have done differently. It never gives advice during a live hand. 5. Make it production-ready. Each feature ships with evaluation sets, monitoring, cost and latency budgets, fallbacks for when a model or provider fails, and a way to roll changes back You'll work with the full-stack engineer, who owns the game server, and directly with the project owner on what to build next. What you bring - 4+ years in software engineering, with 2+ years shipping machine learning or LLM features that real users rely on - Strong Python, and enough TypeScript or JavaScript to work on our Node.js game server - Hands-on experience building with LLM APIs: prompt design, tool use, structured outputs, and evaluating model quality - Experience taking AI features to production: serving, monitoring, cost control, and handling model failures safely - Solid machine learning basics: classification, anomaly detection, and choosing the right metrics for imbalanced data - A habit of measuring: you build test sets before you tune, and you can show whether a change made things better - Good judgement about player trust and privacy: what data to use, what to log, and when a person should make the final call - Clear written English for async work

Find the trade-selection rule of an SPX 0DTE options bot (Python, labeled data provided)
Applied

We follow a rule-based SPX 0DTE options bot that trades day (09:30–16:00 ET) and overnight (20:15–09:25 ET) with the same rules. Each day it publishes a morning report (00:00 ET) and a midday report (08:00 ET) with: pivot point, support, resistance, gravity level, expected range, remaining expected move, market bias, market state, and its own 1-hour Murrey Math levels (support pivot / stability line / equilibrium / buy and sell zones). It also shows a live screen: session direction, 1/5/15/30-min DMI, instant liquidity, walls, and a contract ladder.
We already reproduced most of it: - side = direction of the last 15-min SPX move (+ position vs the report pivot) - trigger = first break of the previous 1-hour candle's high/low in that direction, price holding ~45–60 s beyond it - contract = nearest OTM SPXW with ask ≤ $4.00; stop = 50%, targets T1–T7, add after a fast T1 - we rebuilt their report (14/17 numbers match) and their screen Our replica fires ~10 signals per night; the bot takes ~4 and skips the rest. We need the missing FILTER that decides which signals it takes, plus the few entries that are not prev-hour breaks (e.g. rebounds to a Murrey line). You get: every signal since 5 Oct labeled taken/skipped, 1-s SPX and option quotes, our live screen fields per minute, all daily reports (theirs and ours), chart images, and the bot's entry/exit times. Acceptance: 1) fit on 5–19 Oct only; we score once on unseen days (20–23 Oct) 2) Final acceptance is LIVE: your rule runs on our live screen data for 3 trading days (day + overnight) and must match the bot's real entries as they happen. Pass = precision ≥ 40% and recall ≥ 50% per session, entry within 60 s. The rule must be causal and delivered as plain logic + a Python function. Payment: fixed price in 2 milestones; the second is paid only after the live test passes. Skills: Python, pandas, scikit-learn, intraday options trading; TradingView/Pine Script a plus.

BIGEdge™ is built on data, models and intelligence. We have an MVP and are now moving toward GA.
We are looking for a senior Data Scientist to lead the data science behind BIGEdge and own the models, scoring methodology, data quality and intelligence layer that power the platform. We are open to a fractional/part-time engagement with the right person. This could be an ongoing role rather than a traditional full-time position. We are a small team, so this is a highly hands-on role. You should be equally comfortable setting direction with the founders and Product team, challenging methodology and priorities, and then getting into the weeds to inspect data, write code, test models, troubleshoot issues and improve performance yourself. You will work closely with our Lead Engineer, who owns the application and platform layer, while you own the data, AI and intelligence layer. What You’ll Own MVP to GA Assess the current MVP data and model architecture and identify what needs to change before GA Strengthen model accuracy, validation, Data Sufficiency and monitoring Improve onboarding, data-source reliability and production readiness Help prioritize what needs to be completed for GA versus what can wait Ensure the intelligence layer can scale across more companies, sources and users Models, Scoring & Validation Own and improve BIGEdge’s scoring, classification and intelligence models Lead work across lever classification, risk, sentiment, Employee Commitment, Customer Advocacy, intent and AI-generated insights Own the statistical methodology behind BIGEdge scores and outputs Measure model performance by lever and category using appropriate measures such as precision, recall, false positives, thresholds and agreement Build and maintain validation approaches including golden sets, held-out testing and human review Identify weak models, edge cases and areas where performance needs to improve Own Data Sufficiency methodology and determine when there is enough evidence to support a score or insight Monitor model performance and lead recalibration or retraining where needed Make sure our models and scores can be explained, tested and trusted Data Sources & Quality Own the strategy for how BIGEdge uses external, customer-provided and internal data Assess source quality, coverage, bias and dependency Understand how results change when source coverage changes or a source becomes unavailable Help determine how different types of data should be used, compared or combined Establish standards for data quality, relevance, recency, deduplication and entity matching Work with Product and Legal on data provenance, vendor dependencies and appropriate use of third-party data NLP, Machine Learning & AI Develop and improve NLP and machine-learning models used to classify and interpret unstructured text Refine taxonomies and classification logic across Leadership, Culture and Reputation Evaluate and improve traditional ML and LLM-based approaches Support RAG, retrieval and AI-agent capabilities where they improve the product Improve model accuracy, explainability and reliability Establish strong practices for deployment, monitoring and model lifecycle management Data Platform & Onboarding Improve the data architecture across ingestion, processing, storage and access Build and maintain reliable data pipelines across multiple sources Own the data setup and onboarding process for new companies, including company and competitor setup, source configuration, historical backfill, validation and readiness for scoring Partner with Engineering to integrate model outputs into the product Help ensure the platform can scale as the number of companies and data sources grows Product & Client Intelligence Turn raw data into structured insights that are useful in the product and in client delivery Make sure scores, themes, trends, benchmarks and insights are supported by the underlying data Work with Product to make data and AI outputs understandable and useful Work with Advisory to translate data into meaningful client insights without overstating what the evidence supports Help evolve the proprietary intelligence and methodology that differentiates BIGEdge How You’ll Work Operate as the primary Data Scientist in a small team Move comfortably between senior-level strategy and hands-on technical work Challenge methodology, recommend changes and help implement them Take ownership from problem definition through analysis, build, validation and production Get into the detail when something does not look right, whether that means reviewing data, debugging a pipeline, testing a model or inspecting individual classifications Partner closely with the Lead Engineer, Product, Advisory and leadership Explain complex technical issues clearly to non-technical stakeholders Document models, methodology and processes so critical knowledge is not held by one person What You Bring 7+ years of experience in data science, machine learning, AI or related roles Strong foundation in statistical modelling and model validation Strong Python and SQL skills Strong experience with NLP, text classification and unstructured data Experience evaluating multi-label classification systems, taxonomies or similar frameworks Strong understanding of precision, recall, false positives, threshold setting and model performance Experience taking ML or AI models from development into production Experience with LLMs, RAG and modern AI approaches Experience with cloud infrastructure, preferably GCP Experience with production data pipelines and MLOps Comfortable working with noisy, incomplete and multi-source data Strong ability to translate technical results into business insight Comfortable taking ownership and working independently Nice to Have Experience building scoring models, indices or proprietary analytical frameworks Experience with alternative data, web-derived data or multi-source external datasets Experience with employee, customer, reputation or people-related data Experience with survey data and open-text analysis Experience with causal inference, experimentation or advanced statistical methods Experience working in an early-stage or product-led environment Experience supporting products used by senior executives, boards or investors What to Expect This is an important role for BIGEdge. You will have a direct impact on the quality of the data, models and insights our clients see. We are looking for someone who is deeply technical but practical, who cares about whether the data is actually right, and who can help us take BIGEdge from MVP to GA and beyond. We are open to structuring this as an ongoing fractional engagement for the right person.
